-//! of `App` when we eventually try to call certain methods on either the `component_systems` or

-//! That of course lead me to split this structure up. I didn't and still don't like this because

-//! to grow over time. And I, ideally, want a single place to put it all.
-//!
-//! So, this module here is my attempt at trying to formalize this a bit more and do a bit of
